What Does Your Poop Say?

Hippocrates famously wrote, “All diseases begin in the gut,” but is there any truth to it?

It turns out Hippocrates was wise before his time in recognizing how much influence the digestive system has on our overall health. That wisdom was forgotten for a long time, but in recent decades, research has increasingly confirmed how “the gut” impacts nearly every aspect of the body. These include mental health, the immune system, inflammation, hormone balance, and of course, nutrient absorption.

One of the most effective ways to assess the impact the gut is having on the body is by evaluating your stool (yep, we want to check out your poop!). The GI-MAP stool test has become a cornerstone in our practice to better understand how gut health influences many aspects of wellness.

What is the GI-MAP Test?

The GI-MAP test is a stool analysis ordered by a functional practitioner and completed in the privacy of your home.

It uses quantitative PCR (qPCR) technology to measure DNA from over 30 bacterial species (the good, the bad, and everything in between), key fungal markers (including Candida species), parasites, and markers of digestion and immunity. Understanding how to interpret each section empowers us to turn this data into actionable insights that optimize your gut health.

Let’s Talk About Gut Microbes

Your gut is home to trillions of microbes—most of which are bacteria, but also fungi and parasites. Whether these microbes are helpful or harmful depends on their type and how many are present. We categorize them as commensal (good bacteria), opportunistic (can become problematic), and pathogenic (clearly harmful). Understanding which microbes fall into each category is essential for interpreting clinical significance.

A healthy gut features high commensal abundance, minimal opportunistic overgrowth, and absence of pathogens or fungal overload.

Deciphering Digestion

Digestion is the multi-step process by which the body breaks down food and drink into absorbable nutrients—amino acids, simple sugars, fatty acids, vitamins, and minerals. These nutrients are then absorbed into the bloodstream to be used for energy, growth, repair, and cellular function.

Digestion begins with chewing (mechanical digestion). After swallowing, you shouldn’t feel digestion happening, but much is going on behind the scenes.

Stomach acid (hydrochloric acid) initiates chemical digestion by breaking down food bonds. This acid also triggers bile secretion from the gallbladder and enzyme production from the pancreas. Bile helps digest fats, while various enzymes break down proteins, fats, and carbohydrates into absorbable units.

Because digestion is complex, it’s not uncommon for parts of the process to go awry. The GI-MAP test helps pinpoint where issues may be occurring.

• H. pylori: Presence may indicate low stomach acid, affecting digestion downstream.
• Steatocrit: Helps assess fat malabsorption, gallbladder or pancreatic insufficiency, or damage to intestinal membranes.
• Elastase: Indicates pancreatic enzyme output—are you producing enough enzymes to digest your food?

What About the Immune System? Is It in the Gut Too?

Absolutely. About 80% of your immune system resides in your gut. Think about it: the gut is where foreign substances (food, drink, bacteria) regularly enter the body, so the immune system stays active and alert here.

The GI-MAP includes markers to assess immune function:

• Secretory IgA (sIgA): The main immune defense in your gut lining. Elevated levels may indicate infection or allergy. Low levels may reflect chronic stress, adrenal insufficiency, or immune exhaustion—leaving you vulnerable to pathogens.
• Calprotectin: Measures neutrophils in the large intestine, a sign of inflammation.

Who Is GI-MAP Testing For?

• Individuals with chronic gastrointestinal symptoms (bloating, diarrhea, constipation, abdominal pain, gas)
• Patients with non-GI issues linked to gut health (autoimmune conditions, skin disorders, mood imbalances)
• Those who’ve tried conventional therapies (e.g., antibiotics, PPIs) without full resolution

Why Should You Invest in GI-MAP Testing?

If you’re experiencing symptoms—bloating, discomfort, reflux, autoimmune flares, skin conditions, or mood shifts—this test helps you test, not guess. It goes beyond symptom-based treatment to offer a clear picture of what’s happening in your gut and how to address it effectively.

How Do You Get the Test Kit?

1. Once you decide to move forward, the lab ships a stool collection kit with detailed instructions and prepaid return packaging.
2. You collect a small sample, seal the tube with preservative, and return it under ambient conditions.
3. Within 48–72 hours of receipt, the lab analyzes the DNA and data from your sample.
4. When complete, we both receive a PDF report showing your results and how they compare to reference ranges. Based on your unique profile, we develop a 3–6 month personalized plan that includes dietary shifts and a supplement protocol.

Armed with the data from your GI-MAP test, you’re no longer guessing—you’re healing.
